摘要： A power supply voltage detection circuit includes a voltage division circuit for linearly dividing a power supply voltage, a reference voltage circuit for providing a reference voltage, and a comparison circuit for comparing the output voltage from the voltage division circuit and the reference voltage from the reference voltage circuit. The power supply voltage detection circuit outputs a signal upon detecting that the power supply voltage is equal to or higher than the reference voltage. A PMOS transistor is provided between the voltage division circuit and the comparison circuit. The PMOS transistor includes a source terminal connected to an output terminal of the voltage division circuit, a drain terminal connected to an input terminal of the comparison circuit, and a gate terminal connected to the ground. Until the output voltage from the comparison circuit is higher than the threshold voltage of the PMOS transistor, the PMOS transistor remains OFF, thereby canceling the input of the output voltage signal from the voltage division circuit to the comparison circuit. Thus, without using external components, the signal is prevented from being erroneously output due to the output voltage from the voltage division circuit rising over, without crossing, the reference voltage from the reference voltage circuit during a sharp rise of the power supply voltage.

摘要： During an intermittent operation mode, a switch is normally opened and a capacitor with a large capacitance is isolated from a circuit. Under this condition, a power source voltage is intermittently supplied to a driven device. Since a charge/discharge current of the capacitor during the intermittent operation mode is limited to the charge/discharge current of the capacitor with a small capacitance, the power consumption can be lowered. In addition, since no switch exists in the current path from a power source voltage conversion circuit to the driven device, there is no drop, due to a switch, in the voltage supplied from the power source voltage conversion circuit to the driven device. On the other hand, during a continuous operation mode in which power source voltage is continuously provided to the driven device, the switch is normally closed and a capacitor with a large capacitance is connected to the power source system. Then the noise level in the supplied power is lowered.

摘要： In a switching regulator, switching noise is reduced with keeping high conversion efficiency. The switching regulator includes plural output switching transistors 21 through 23 having different on-resistances, which are operated nadescending order of on-resistance in the on operation and are operated in an ascending order of on-resistance in the off operation. In this manner, abrupt current change can be suppressed in the switching operation, resulting in reducing di/dt noise derived from a parasitic inductor 102.

摘要： The switching regulator of a synchronous rectifying mode comprises the first and second switches SW1, SW2 arranged in series between the power source Vdd and the ground Vss, the switch control unit 1 which controls the on-off operation of the switches SW1, SW2, and the smoothing circuit 4 which smoothes the output node potential Vnd. When the signal Sc1 indicates that the output node potential Vnd goes below the first reference potential Vr1 which is the reference to detect the occurrence of the inrush current while the first switch SW1 is in the ON state, the control circuit 10 turns off the first switch SW1. Thus, the detection of the inrush current is conducted by making use of a voltage drop due to the on resistance of the first switch SW1, so that it is unnecessary to provide a resistance element for detecting the inrush current.

摘要： A bare-chip IP of a multi-chip module and an external device of the multi-chip module are interfaced with each other through a dedicated I/O bare-chip IP. Each of the bare-chip IPs other than the dedicated I/O bare-chip IP is not provided with an interface circuit for connection to the external device, and thus is only required to have a withstand voltage characteristic corresponding to the operating voltage of an internal circuit. As a result, it is only necessary to provide, on the bare-chip IPs, transistors of a few kinds of withstand voltage characteristics.

摘要： A power circuit including means for preventing the generation of an inrush current during the power circuit's initial operation without increasing the size of the power circuit is described. The power circuit comprises an output transistor for supplying a current from a power supply to an output terminal, and a differential amplifier for controlling the current supplied by the output transistor in such a manner as to regulate a voltage at the output terminal based on a preset reference voltage. A limiting transistor is provided as a source follower on a current path at the output stage of the differential amplifier. The gate potential of the output transistor is controlled using the source potential of the limiting transistor. Before the power circuit starts to operate, an operation controller charges a capacitor to control the gate potential of the limiting transistor so that during the initial operation of the power circuit, the capacitor is discharged by using a current source. Accordingly, during the initial operation of the power circuit, the gate potential of the limiting transistor gradually decreases while the gate-source voltage of the output transistor gradually increases. As a result, the generation of the inrush current can be suppressed.
